Overview
Sichuan wastewater treatment plant serves 577,800 people in Banzang Street, Zigong, Sichuan, China. It operates under China's national wastewater regulations for large agglomerations.
The Sichuan wastewater treatment plant is located in Banzang Street, a subdistrict of Zigong in Sichuan Province, China. It serves a population of 577,800, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated in the urban area of Zigong, near the G85 expressway, and plays a key role in treating municipal wastewater for the region. As a large-scale facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets stringent limits on effluent quality. For plants serving over 500,000 people, advanced treatment with nutrient removal is typically required to protect receiving waters. Its scale implies a robust infrastructure to handle high flows. The treated effluent likely discharges into a local waterway within the Yangtze River basin, as Zigong is part of the upper Yangtze system. The plant's operation is critical for protecting downstream aquatic ecosystems and ensuring water quality in the region's rivers, which ultimately flow into the East China Sea.
Environmental context
The plant's receiving water body is likely a tributary of the Tuo River, which flows into the Yangtze River. The Yangtze basin supports diverse aquatic life, including endangered species such as the Chinese sturgeon and finless porpoise. Effluent from the plant must meet strict nutrient limits to prevent eutrophication in downstream lakes and reservoirs, which are important for drinking water and fisheries.
